It's been a while since the the update, but I've had a more time lately. MSC also provided a copy of MSC Nastran free of charge to help support the project, so modern MSC Nastran support is much better.

Finally, the GUI has receieved a lot of work recently including:

  • Better results selector. Individual displacment and SPC/MPC/Load Vector components are selectable.
    For solid, plate, and composite stress/strain, nodal or centroidal stress
    may be shown and various blending methods including nodal averaging is now supported.
  • Grid Point Forces
    are supported in the GUI. They take some getting used to but you can march along a vector and output the section loads in any arbitrary coordinate system.
  • Preferences are also now exposed in a json file (vs the registry) and if you find
    a bug in the new results, you can flip a flag to use the old objects.
  • A recent files history to speed up model loading and a whole bunch of other bug fixes.

Programmatics:

  • Supports Python 3.9 - 3.12 (later versions of Python requires downloading from github)
  • GUI is compatible with VTK 9 and PyQt5/PySide2
  • improved testing of old versions of packages
  • much improve NX 64-bit and OptiStruct support

BDF:

  • fixed CAERO1 paneling bug
  • 427 cards supported (up from 405)

OP2:

  • 20 new results
  • vectorized op2 writing
  • model.cquad4_stress is now found in model.op2_results.stress.cquad4_stress. Same goes for other stress, strain, force, and strain_energy components. This will hopefully make things a bit easier find.

GUI:

  • grid point forces / section cuts / shear-moment torque plotter
  • more dynamic stress/strain results allow for simpler menus
  • transient/complex fringe only animations now supported
  • recent files support
  • greatly expanded preferences menu; many more preferences are saved
  • new icons
